LCG, November 26, 2025--RWE announced today the commissioning of the Stoneridge Solar project, located in Milam County, Texas. The project capacity is 200 MW of solar power, plus a battery energy storage system (BESS) that provides 100 MW (200 MWh) of battery storage capacity. The BESS improves the supply of short-term, reliable, affordable electricity in ERCOT.

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

Long Ridge Energy Announces Plans to Allow Transition to 100 Percent Hydrogen
LCG, March 4, 2021--Ohio's Long Ridge Energy Generation is retrofitting its 485-MW combined-cycle power plant to use a blend of natural gas and carbon-free hydrogen, making it the nation's first large gas turbine plant to transition operations to hydrogen fuel. Long Ridge, with Black & Veatch as program manager, is working to modify the plant to use a mix of natural gas and hydrogen in the GE 7HA.02 combustion turbine after it begins commercial operations in August 2021.
As the first worldwide plant to blend hydrogen in a General Electric H-class gas turbine, the Hannibal, Ohio-based site initially will burn five percent hydrogen by volume in the natural gas stream. The hydrogen program will outline the changes necessary to transition to use 100 percent green hydrogen over the next decade. Green hydrogen uses renewable power and electrolyzers to separate water into its oxygen and hydrogen elements. Thus as the facility transitions towards using 100 percent green hydrogen, it will transition towards effectively 100 percent renewable power.
With a goal of carbon-free baseload power production, Black & Veatch is providing expertise in the development of the plant's hydrogen integration strategy to ensure safe, reliable industrial practices for the site. The plant also will serve as a key component of a low-carbon industrial complex that will sell power to on-site tenants and third parties seeking to decarbonize and balance their power resources.
Long Ridge Energy's president outlined its hydrogen strategy, "As the number of companies with carbon-free energy goals continues to grow, we decided to make Long Ridge the first in the U.S. to burn hydrogen in a large gas turbine. We want to accelerate the transition to hydrogen as quickly as possible."
The project reflects Long Ridge's long-term commitment to providing clean energy against a backdrop of growing demands by industry stakeholders for decarbonized power. The Long Ridge site is ideally situated along the Ohio River with industrial byproduct hydrogen readily available in the Ohio River valley. Its location at a port facility allows a quick-to-market solution while underground salt deposit geology can provide carbon or hydrogen storage. The river also provides an ample resource for production of green hydrogen.
Once completed, the Long Ridge Energy Generation Project will be among the world's lowest emission baseload power plants of any type while being compact, low-impact and significantly more advanced than earlier generations of natural gas plants.
